Interface UserRegistry

All Superinterfaces:
Remote
public interface UserRegistry extends Remote
Registries. This should extend java.rmi.Remote as the registry can be in a remote process.

Implementation of this interface must provide implementations for:

  • initialize(java.util.Properties)
  • checkPassword(String,String)
  • mapCertificate(X509Certificate[])
  • getRealm
  • getUsers(String,int)
  • getUserDisplayName(String)
  • getUniqueUserId(String)
  • getUserSecurityName(String)
  • isValidUser(String)
  • getGroups(String,int)
  • getGroupDisplayName(String)
  • getUniqueGroupId(String)
  • getUniqueGroupIds(String)
  • getGroupSecurityName(String)
  • isValidGroup(String)
  • getGroupsForUser(String)
  • getUsersForGroup(String,int)
  • createCredential(String)

Users of this interface should have the role-based permissions for the Administrator.

The exceptions thrown by the methods in this class are:

Each exception type is a recommendation to the Custom Registry developer on it's use case. e.g. EntryNotFoundException should be used when the entry can not be found. There is no requirement that the recommendation be followed. As such, code which invokes registry APIs should handle all thrown exceptions accordingly.

The exceptions thrown by the Custom Registry implementations may be wrapped by the WebSphere code in this release. It is recommended that any exceptions that are thrown be checked for the cause with getCause().

  • Method Details

    • initialize

      void initialize(Properties props) throws CustomRegistryException, RemoteException
      Initializes the registry. This method is called when creating the registry.
      Parameters:
      props - the registry-specific properties with which to initialize the custom registry
      Throws:
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • checkPassword

      String checkPassword(String userSecurityName, String password) throws PasswordCheckFailedException, CustomRegistryException, RemoteException
      Checks the password of the user. This method is called to authenticate a user when the user's name and password are given.
      Parameters:
      userSecurityName - the name of the user or userid or a registry-unique identifier
      password - the password of the user
      Returns:
      a valid userSecurityName. Normally this is the name of same user whose password was checked but if the implementation wants to return any other valid userSecurityName in the registry it can do so
      Throws:
      PasswordCheckFailedException - if userSecurityName/ password combination does not exist in the registry
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • mapCertificate

      String mapCertificate(X509Certificate[] cert) throws CertificateMapNotSupportedException, CertificateMapFailedException, CustomRegistryException, RemoteException
      Maps a Certificate (of X509 format) to a valid user in the Registry. This is used to map the name in the certificate supplied by a browser to a valid userSecurityName in the registry
      Parameters:
      cert - the X509 certificate chain
      Returns:
      the mapped name of the user userSecurityName
      Throws:
      CertificateMapNotSupportedException - if the particular certificate is not supported.
      CertificateMapFailedException - if the mapping of the certificate fails.
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getRealm

      String getRealm() throws CustomRegistryException, RemoteException
      Returns the realm of the registry.
      Returns:
      the realm. The realm is a registry-specific string indicating the realm or domain for which this registry applies. For example, for OS400 or AIX this would be the host name of the system whose user registry this object represents. If null is returned by this method realm defaults to the value of "customRealm".
      Throws:
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getUsers

      Result getUsers(String pattern, int limit) throws CustomRegistryException, RemoteException
      Gets a list of users that match a pattern in the registry. The maximum number of users returned is defined by the limit argument.

      This method is called by GUI(adminConsole) and Scripting(Command Line) to make available the users in the registry for adding them (users) to roles.

      Parameters:
      pattern - the pattern to match. (For e.g., a* will match all userSecurityNames starting with a)
      limit - the maximum number of users that should be returned. This is very useful in situations where there are thousands of users in the registry and getting all of them at once is not practical. A value of 0 implies get all the users and hence must be used with care.
      Returns:
      a Result object that contains the list of users requested and a flag to indicate if more users exist.
      Throws:
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getUserDisplayName

      String getUserDisplayName(String userSecurityName) throws EntryNotFoundException, CustomRegistryException, RemoteException
      Returns the display name for the user specified by userSecurityName.

      This method may be called only when the user information is displayed (i.e information purposes only, for example, in GUI) and hence not used in the actual authentication or authorization purposes. If there are no display names in the registry return null or empty string.

      In WAS 4.0 custom registry, if you had a display name for the user and if it was different from the security name, the display name was returned for the EJB methods getCallerPrincipal() and the servlet methods getUserPrincipal() and getRemoteUser(). In WAS 5.0 for the same methods the security name will be returned by default. This is the recommended way as the display name is not unique and might create security holes. However, for backward compatability if one needs the display name to be returned set the property WAS_UseDisplayName to true.

      See the Infocenter documentation for more information.

      Parameters:
      userSecurityName - the name of the user.
      Returns:
      the display name for the user. The display name is a registry-specific string that represents a descriptive, not necessarily unique, name for a user. If a display name does not exist return null or empty string.
      Throws:
      EntryNotFoundException - if userSecurityName does not exist.
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getUniqueUserId

      String getUniqueUserId(String userSecurityName) throws EntryNotFoundException, CustomRegistryException, RemoteException
      Returns the UniqueId for a userSecurityName. This method is called when creating a credential for a user.
      Parameters:
      userSecurityName - the name of the user.
      Returns:
      the UniqueId of the user. The UniqueId for an user is the stringified form of some unique, registry-specific, data that serves to represent the user. For example, for the UNIX user registry, the UniqueId for a user can be the UID.
      Throws:
      EntryNotFoundException - if userSecurityName does not exist.
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getGroups

      Result getGroups(String pattern, int limit) throws CustomRegistryException, RemoteException
      Gets a list of groups that match a pattern in the registy. The maximum number of groups returned is defined by the limit argument.

      This method is called by GUI(adminConsole) and Scripting(Command Line) to make available the groups in the registry for adding them (groups) to roles.

      Parameters:
      pattern - the pattern to match. (For e.g., a* will match all groupSecurityNames starting with a)
      limit - the maximum number of groups that should be returned. This is very useful in situations where there are thousands of groups in the registry and getting all of them at once is not practical. A value of 0 implies get all the groups and hence must be used with care.

      Returns the Unique id for a group.
      Parameters:
      groupSecurityName - the name of the group.
      Returns:
      the Unique id of the group. The Unique id for a group is the stringified form of some unique, registry-specific, data that serves to represent the group. For example, for the Unix user registry, the Unique id could be the GID.
      Throws:
      EntryNotFoundException - if groupSecurityName does not exist.

      List<String> getGroupsForUser(String userSecurityName) throws EntryNotFoundException, CustomRegistryException, RemoteException
      Returns the securityNames of all the groups that contain the user

      This method is called by GUI(adminConsole) and Scripting(Command Line) to verify the user entered for RunAsRole mapping belongs to that role in the roles to user mapping. Initially, the check is done to see if the role contains the user. If the role does not contain the user explicitly, this method is called to get the groups that this user belongs to so that check can be made on the groups that the role contains.

      Parameters:
      userSecurityName - the name of the user
      Returns:
      a List of all the group securityNames that the user belongs to.
      Throws:
      EntryNotFoundException - if user does not exist.
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • getUsersForGroup

      Result getUsersForGroup(String groupSecurityName, int limit) throws NotImplementedException, EntryNotFoundException, CustomRegistryException, RemoteException
      Gets a list of users in a group.

      The maximum number of users returned is defined by the limit argument.

      This method is being used by the WebSphere Application Server Enterprise Process Choreographer (Enterprise Edition) when staff assignments are modeled using groups.

      In rare situations if you are working with a registry where getting all the users from any of your groups is not practical (for example if there are a large number of users) you can throw the NotImplementedException for that particualar group(s). Make sure that if the WAS Choreographer in installed (or if installed later) the staff assignments are not modeled using these particular groups. If there is no concern about returning the users from groups in the registry it is recommended that this method be implemented without throwing the NotImplemented exception.

      Parameters:
      groupSecurityName - the name of the group
      limit - the maximum number of users that should be returned. This is very useful in situations where there are lot of users in the registry and getting all of them at once is not practical. A value of 0 implies get all the users and hence must be used with care.
      Returns:
      a Result object that contains the list of users requested and a flag to indicate if more users exist.
      Throws:
      NotImplementedException - throw this exception in rare situations if it is not pratical to get this information for any of the group(s) from the registry.
      EntryNotFoundException - if the group does not exist in the registry
      CustomRegistryException - if there is any registry specific problem
      RemoteException - as this extends java.rmi.Remote

    • createCredential

      com.ibm.websphere.security.cred.WSCredential createCredential(String userSecurityName) throws NotImplementedException, EntryNotFoundException, CustomRegistryException, RemoteException
      This method is implemented internally by the WebSphere code in this release. This method is not called for the Custom Registry implementations for this release. Return null in the implementation.

      Note that since this method is not called one can also return the NotImplementedException as the previous documentation says.

      Throws:
      NotImplementedException
      EntryNotFoundException
      CustomRegistryException
      RemoteException
